  • Disko Island as a Test-bed for Carbon Pathways


  • A team of four scientists—P.I. Dr. Claire Cousins, Dr. Sami Mikhail, and PhD students Casey Bryce and Mark Fox-Powell—spent two weeks in August of 2013 sampling basalts and thermal spring materials on Disko Island, Greenland. The primary goal of this work was to collect a robust sample set to support ongoing research of interest to the DCO community.

    Disko presents an ideal field site due to its unusual basalts, whose compositions are rare for surface samples, containing FeNi alloys and Fe-carbides. Study of these basalts may lead to increased understanding of their formation. Additionally, Disko is home to many understudied deep thermal springs, including mud volcanoes, salt springs, and cold to warm springs. The investigation of the microbes within these thermal springs may provide insights into subsurface microbiological communities’ carbon pathways and life cycles.

    Due in part to its remote location, Disko Island is relatively under-examined. Many of the logistical issues addressed by this team will be invaluable to researchers coming to the island for future study.
